3 Alimentos que Danificam Seus Rins!

00:00 The kidneys are the filters of our body. They eliminate toxins, participate in the
balance of various substances, and allow the proper functioning of the organism. You may know someone who undergoes hemodialysis,
and if you don’t, let me tell you that the quality of life for these people decreases
significantly. Imagine being connected to a hemodialysis
machine for at least three hours a day, at least three times a week. It becomes practically impossible to travel
due to the logistics involved. That’s why today we are going to talk about
three foods that can damage your kidneys. You
00:41 will be surprised by what is on our list. These foods are present in people’s daily
diets. At the end of the video, I will suggest some
foods that you can include in your diet to promote the proper functioning of your kidneys. Hello, I’m Dr. Tiago, a urologist here in
São Paulo. Let’s start with the first food on our list,
which is salt. Salt is a widely used seasoning in our kitchen,
and the salt we use is sodium chloride. The main villain here is sodium. 01:19 This study here conducted a thorough
analysis of what we have in the medical literature regarding salt consumption and kidney problems. There is a significant correlation between
the amount of sodium consumed by people and the development of chronic kidney disease,
in other words, the loss of kidneys. This association can be direct, as excess
sodium can cause direct damage to the kidneys, or indirect, because we know that excessive
sodium consumption is the main cause of hypertension, or high blood pressure. 01:58 Hypertension accounts for 25% of the
cases, making it the second leading cause of chronic kidney disease, or in other words,
the second most common cause of kidney loss in people. Every time you consume excess sodium, you
are indeed damaging your kidneys. In addition, excessive sodium consumption
increases the formation of kidney stones. Every time you have an excess of sodium consumption,
through regulatory mechanisms within our kidneys, the kidneys start to increase the excretion
of calcium, which favors the formation and emergence of kidney stones. The recommended limit for sodium consumption
is not to exceed three grams of sodium chloride, which corresponds to five grams of salt. So, if you measure your salt intake, you should
not consume more than five grams of salt daily to stay within the recommended daily sodium
intake. The second food is sugar. That’s right, sugar can also damage your kidneys. Every time you consume excessive sugar, your
body needs to increase insulin production to normalize blood sugar levels. Insulin is the main hormone responsible for
regulating the amount of glucose in our blood. This is what we call pre-diabetes when a patient
has normal blood sugar levels but increased insulin levels. The patient starts to develop what we call
insulin resistance, where the body becomes resistant to the action of the hormone despite
having normal or near-normal blood sugar levels. This leads to metabolic changes in our kidneys,
making them work harder to regulate our body systemically. If you continue consuming sugar, you can progress
from the stage of pre-diabetes to full-blown diabetes, and diabetes is the main disease
that causes chronic kidney disease, in other words, the disease that causes the most kidney
loss in people. As you can see in this graph, diabetes accounts
for approximately 40% of the cases of chronic kidney disease. In other words, four out of every ten people
who lose their kidneys do so due to diabetes. So, avoid the consumption of sugar, especially
refined sugar. You might be questioning that you don’t consume
sugar directly, but you have to remember that our diet includes a lot of carbohydrates,
such as bread, pasta, and potatoes. All these foods, after digestion, turn into
sugar in our blood. That’s right, all carbohydrates, when metabolized,
turn into sugar in our blood, and today our diet is very high in carbohydrate consumption,
which increases our glycemic load, that is, the amount of sugar in our blood to levels
that our body cannot tolerate. Therefore, we have an increasing number of
patients with pre-diabetes and diabetes. So, you can consume carbohydrates, but in
moderate amounts, ideally calculated by a nutritionist according to your needs. Avoid excessive consumption of these types
of foods because they can lead to pre-diabetes, diabetes, and kidney loss. And third, on our list, we have processed
foods. First, let me explain what processed foods
are. Any food that contains added sugar, salt,
additives, preservatives, or fats is considered a processed food. Let’s think about the daily menu of someone
like Sueli. Sueli is a 35-year-old woman who, in the morning,
has bread with butter and drinks one of those powdered fruit drinks. In the mid-morning, she decides to have a
yogurt along with one of those boxed juices since she wakes up very early and needs a
meal in the middle of the morning. For lunch, she has a somewhat balanced meal,
with meat, rice, French fries, and half a cup of soda. In the afternoon, she has a cookie or biscuit
with another boxed juice. And in the evening, when she arrives home
tired from work and doesn’t feel like cooking, she decides to eat one of those frozen lasagnas
that we buy, ready-made. Can you identify with any of these types of
food? I mentioned this to you because just in this
diet, Sueli consumed at least seven processed foods. This has become very common, as it is much
easier for us to consume this type of food. And what are processed and ultra-processed
foods? Here is a list, starting from the most obvious
to those that you probably don’t think are processed foods. So, here they are: instant noodles, frozen
lasagnas, sodas (soft drinks), which is an important detail, as most sodas contain phosphoric
acid, which is extremely harmful to the kidneys and greatly increases the chance of developing
kidney stones, combined with other factors. Other processed foods include sausages, condiments,
cereals, ice cream, cakes, cookies, toasts, and even sliced bread. That’s right, sliced bread is also considered
a processed food because it requires additives to make it last longer. Here’s a test for you: buy bread from a bakery,
which was made at the time, and leave it at home to see how long it lasts. Then compare it with the sliced bread you
buy at the market, which is made by the industry. You will see that sliced bread lasts longer. If you don’t believe what I’m saying, this
study that will appear on your screen shows an association between the consumption of
processed foods and the likelihood of developing chronic kidney disease, or in other words,
losing your kidneys. This study showed that patients who consumed
more processed foods had a approximately 25% higher chance of developing chronic kidney
disease compared to those who did not consume processed foods. So, we do have data from medical literature
that proves that these foods are harmful to the kidneys. Now you might be wondering if you can eat
anything at all. So, let’s replace these processed foods with
natural foods. Which foods promote kidney health? The first one is citrus juices, obviously,
the natural juices made from fruits. Most boxed juices have a small amount of juice
and contain additives to keep them fresh for longer. So, if you’re going to buy any of these ready-made
juices, make sure they are 100% natural. Citrus juices are rich in citrate, a substance
that helps prevent kidney stone formation and promotes good kidney health. Second, we have fruits and vegetables. Natural foods are practically all good for
renal function. Another type of food is yogurt. But wait, yogurt is a processed food. Calm down. You need to look at what type of yogurt you
are consuming. I’m talking about plain yogurt, not the flavored
ones. Flavored yogurts are considered processed
foods. But plain yogurt, made with milk and ferment,
is a natural food and can be used as a good source of calcium. It is even considered a probiotic food that
helps with the health of your intestines and kidneys. And finally, sources of protein, such as meat,
eggs, dairy products, fish, and white meat. All natural protein sources are good for your
kidneys, as long as they are not
processed meats like sausages or salami. Oh, but doesn’t protein harm the kidneys? It can harm the kidneys when
you consume very high amounts of protein, usually
above 2 to 3 grams per kilogram of body weight per day. But in 90% of cases, people do not reach the
recommended protein intake, which is around 1 gram per kilogram of body weight per day. So, on average, a person weighing 70 to 75
kilograms needs to consume 70 to 80 grams, up to 100 grams of protein, which is a considerable
amount. And most people do not achieve that because,
in reality, they replace protein with carbohydrates, which, as I mentioned earlier, turn into sugar
and can harm the kidneys. Therefore, increasing protein consumption
is beneficial for kidney health. So, those are the three types of foods that
can harm your kidneys, that can damage your kidneys and lead to chronic
kidney disease and the need for hemodialysis. This is an extremely disabling disease that
significantly reduces people’s quality of life. Listen to me, don’t let yourself develop chronic
kidney disease. Take care of your health, share this video
